Cause every ingame day my server has an event that spawns Boss Monsters at a certain pos and the game remembers the pos where it spawned the monsters ... but when the event is over it is supposed to REMOVE all remaining Boss Monsters, which it doesn't do when no one is near them it seems

This bug, maybe due to bad internet connection, dunno due to the fact that Minetest detect a king of teleportation from initial spawn point to the spawn point I choose and say something like "cheat detected, teleporting player to 0, 0, 0
